- Quaternion.
- </brief_description>
- <description>
- A unit quaternion used for representing 3D rotations. Quaternions need to be normalized to be used for rotation.
- It is similar to Basis, which implements matrix representation of rotations, and can be parametrized using both an axis-angle pair or Euler angles. Basis stores rotation, scale, and shearing, while Quat only stores rotation.
- Due to its compactness and the way it is stored in memory, certain operations (obtaining axis-angle and performing SLERP, in particular) are more efficient and robust against floating-point errors.
